Oblivia (Japanese: オブリビア地方Oblivia-chihō) is the region in which Pokémon Ranger: Guardian Signs takes place. This region is an archipelago composed of several islands. It has many ruins, and legends. In the past it had temples used to worship Pokémon, such as Arceus. Across Oblivia are monuments that, when lit, form the Ranger Sign for Latias and Latios. Also, in some places there are monuments that, when specific side quests are completed, reveal special signs for certain Pokémon that can join your team.
